Overview
The ISL6146AFUZ-TK is a low voltage OR-ing FET controller manufactured by Renesas Electronics Corporation. It is designed for N+1 power distribution applications, utilizing an internal charge pump to drive N-channel MOSFETs. The device supports operating voltages from 1V to 20V and features a supply current of 40 µA. It operates within a temperature range of -40°C to +125°C and is housed in an 8-MSOP package.
Feature Summary
- Integrates an internal charge pump to efficiently drive N-channel MOSFETs without external components.
- Provides fast fault isolation with turn-off times under 0.3 microseconds for reverse current protection.
- Features user-programmable undervoltage lockout and adjustable OUT-V trip points via external resistors.
Applications
- N+1 Industrial Power Distribution Systems
- Telecom and Data Communication Systems
- Uninterruptible Power Supplies (UPS)
Procurement Notes
Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm component status as the base ISL6146 family has noted end-of-life notices. Ensure compatibility with required MSOP-8 footprint and reflow soldering profiles during integration planning.
Selection Notes
Select this controller for systems requiring low-voltage operation down to 1V with independent bias options. It is suitable for replacing power OR-ing diodes to improve efficiency. Consider the 8-MSOP package constraints and thermal requirements when designing the PCB layout for high-density applications.
Part Context
This component belongs to the ISL6146 family of OR-ing MOSFET controllers. The family includes variants like ISL6146A, B, C, D, and E, differentiated by features such as conduction monitoring and enable logic. The AFUZ variant specifically targets low-voltage applications with MSOP packaging.
Replacement Considerations
Direct substitutes include ISL6146AFUZ-T. Verify pin-to-pin compatibility and electrical parameter equivalence with other ISL6146 family members before substitution.
